UMBRELLA FRME Specfication of Letters Patent.

Patented Feb. 16, 1909.

Application flled December 8, 1908. Serial No. 466,459.

T 0 ali whom tt may concem:

Be it known that I, JAMES Rosi a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and usef'ul Improvements in Umbrellw F rames, of which the following is a specifi cation.

This invention relates to umbrclla trames. The object of the invention isto provide an umbrella frame of such construction that the ribs thereof shall normally be held in such positions that their interference with each other shall be prevented.

Further the object is to provide an u1nbrella franco of such construction that the tibs and stretchers shall automatically free themselves from the stick et the umbrella and from adjacent ribs and stretchers When released from the retaining band by which the parts are usually confined when the um brella is not in use.

Further, the objeet is to provide an umbrella frame of such construction that the parts thereof shall automaticallv separate from each other When released mm a retaining band, and which shall be capable of being as closely bound as a frame of usual construction.

A further object is to provide an umbrella frame having the parts so formed as to automatically separate when released from a retaining band, and wherein no objectionable projections, fiable to injure the cover or detract from the appearance of the article shall be presented When the umbrella is closed and the parts thereof confined.

With these objects in view the invention consists of the novel construction and 211- rangement et arts, substantially as hereinafter describe and claimed.

The invention is illustrated in the accompanying drawings in which:

Figure 1 is a s1de elevation of an umbrella frame containing my invention With the cover thereof removed, showing the positions of the parts When closely confined by a retaining bond; Fig. 2 is a side elevation of an umbrella frame, with the cover thereof removed showing the positions assumed by the parts when the umbrella is closed and the parts thereof are not confined by a retaining band; Fig. 3 is a fragmentary view showin a portion of an umbrella rib and the pre erred form of stretcher used in connection therewith, the parts being enlarged; and Figs. 4 and 5 are views of mod1fied forms of stretchers.

In the illustration, 1 represents an umbrella stick having arranged thereon a runner 2 of any desired construction which is to be retained by spring catches on the stick t0 retain the parts of the umbrella in either an open or a closed position. Connected to the stick by a notch ring 3 are a number of ribs 4 which may be solid or of the common paragon type. The ribs are connected to the runner by stretchers 5, which as usual are each pivotally connected at one end to arib and at the other to the runner.

In umbrellas as ordinarily made, there is always a tendency When closed, for the ribs and stretchers to interfere with each other or with the stick. When this coeurs and pressure is brought on the runner to raise the umbrella the cloth forming the cover is subjected to unnecessary wear and strain frequently resulting in its being torn. WVhen the 1ibs and stretchers are in engagement with each other or With the stick the parts are liable to become bent or broken according to the amount of pressure applied on the runner to raise the umbrella.

T 0 avoid possibility of injury to the parts, my improved frame is so made that when the parts are closely confined they are placed under tension and when released are held in positions separated from each other. One, and the preferred means of accomplishing this, is by 80 forming the end of each stretcher adjacent to the point where it is pivotally connected to a rib that the stretcher normall is held to prevent its extending paralle to the rib. As shown in Fig. 2, the stretcher is bent slightly from the point 6 at which it is pivotally connected to the rib, forming a slightly projecting portion on the outer face of the stretcher which When the parts are brought closely together bears against the rib and puts both the rib and stretcher under slight tension for a considerable portion of the length of each. The bend given the stretcher is preferably in the form of a curve beginnin at the pivot point 6, so that no sharp pro ection tending to produce a defined rotrusion on the outer face of the ri is formed.

When the parts formed as described are releasgd from confinement th4e tension Undet which they are placed is sufficient to efi'ectually separate tne parts and prevent possibility of entanglement.

From an understanding of the invention it will be apparent that various means for obtaining the desired tension may be employed. F or instance, as shown in Fig. i, une end of each stretcher may have formed with it a projection 7 which when the stretcher is moved to be substantially parallel with the rib to which it is connected, will come into contact With the rib and impart to it a slight bond. Again, as shown in Fig. 5, a plate 8 may be bent upon and socnrod to one end of each stretcher. The ends of the plate are in line With each other and are formed With curved faces 9 Which when the parts are closely folded are brought against a rib and serve to put both the r1b and stretcher under slight tension.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an umbrelia frame ribs and stretchors connected together, each stretcher having a bond beginning at a point of connection forming a projecting portion which is brought agamst the -ribs when the parts are closly confined thereby putting them under tension, substantially as described.

2. In an umbrella frame ribsand stretch ers oonnected together, each stretcher having a simple curve beginning at 'the point of connection forming a projecting portion which is br.ought against the rib when the parts are closely confined thereby putting (hem under tension, substantialiy as described.

3. In an umbrella frame ribs and stretchers pivotally connected, each stretcher having its onter end curved forming a projectien on the side adjacent to the rib adapted to place the mombers under tension, sub stantially as descrihed.

4. In an umbrella frame ribs and stretchers connected together, each stretohor having a projecting portion beginning at the point of conneotion, which projection is bronght against the rib when the parts are closely confined thereby putting them under tension, substantially as described.

5. As a new article of manufacture, an umbrella stretcher having a single bend be ginning at the point where it is adapted to be connected to a rib, whereby a projecting portion is formed on its coter face, which portion Wili bear against a rib when the stretchcr is brought in close proximity t0 20 rib.

In testimony whereof I aflix my signature in presence of two witnesses.
